This playful re-imagining of the Thames from Tower Bridge to the sea uses the etymology of place names located along the river and their namesakes from abroad, plays on London names that originated from elsewhere and pulls in places from around the world that sound like they should belong here.

Curtis collages maps together to make fictional hybrids so this artwork is at once familiar and disturbing, making us think about the influence of the Thames beyond the capital and in the imagination. Watch out for the reinstatement of the 1831 London Bridge, brand new estuary islands and another country's Olympic Park.

Take a closer look - part of the map is currently on show on massive boards on the riverside walkway outside Tate Modern.
